CAR-MOVING MECHANISM.

EP'ECIFICATION forming part of Letters Patent No. 745,034, dated November 24, 1903. Application filed September 15,1903. Serial No. 173,225. (No model.)

To all whom, it may concern.-

Be it known that I, JEREMIAH BARNES, a citizen of the United States of America, residing at Rummel, in the county of-Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Car- Moving Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

to This invention relates to certain new and useful improvements in car-moving apparatus; and the invention is particularly designed for the moving of cars a desired or predetermined distance for the purpose of materially facilitating the work of loading cars and at the same time permitting the load to be deposited in the car in the desired position or positions. I

As practiced by me the invention is particularly designed for use in connection with the loading of coal into the cars for shipment. While designed primarily for this purpose, it will of course be evident that. the invention is equally applicable to be used in connection with the loading of any material into the cars where such material is deposited in the cars by the aid of a tipple and chute, as is the general practice in the loading of coal into cars for shipment.

3o Heretofore andbefore my invention it has been the general practice in order to move the cars up, whereby to cause the coal to be deposited at different points in the car to prevent handling of the coal by hand, to loosen the brakes of the car and push the latter or allow it to drift a desired distance and then tighten the brakes and hold the car while a quantity of coal is being deposited therein, this operation being repeated until such time as the car is filled. ltis the practice at many of the mines to arrange a side track adjacent the tipple at an incline, whereby to permit the ready drifting of the cars when the brakes are loosened. Many objections are to be found to this system, chief among which is that it is not always possible, and, in fact, frequently impossible, to stop the car at the desired point, owing to the slippery condition of the rails or other conditions which prevent the checking of the car. In event of the car drifting past the desired point considerable labor is required to push the car back to the desired point, especially if the side track is arranged at an incline, as above stated. It

is seldom that an engineis at hand to handle the cars While being loaded, and consequently the return of the car to the desired point is exceedingly difficult.

It is the object of my invention to overcome all these difficulties and provide means whereby one man may readily control the car, so as to permit the same to be moved up as desired to receive the material being placed in the car in order that it may be evenly filled, and to provide means whereby in event of the car drifting past any desired pointit may be returned to the desired point with very little labor or trouble.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and, wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a diagrammatical view of the device as applied to the coal-tipple, showing a car in side elevation. Fig. 2' is a top plan view of the same. Fig. 3 is a top plan view of the device detached. Fig. 4 is a partial longitudinal section and side View thereof. Fig. 5 is a sectional view through one of the drum' shafts, showing a part of one of the levers in side elevation. Fig. 6 is a detail side elevation of the dog-disengaging cam for one of the ratchets, showing the dog in cross-sect-ion and a part of the support in side elevation.

In the present illustration of my invention I have shown the same as used in connection with loading of coal at a coal-nipple, and in the construction of these tipples it is usual'go to employ the lower beam or beams l and the upper or intermediate beam or beams 2, on which latter the device is rigidly secured.

As is well known, the side track is laid directly in front of the tipple, 3 and the chute (not shown) leads from the mine-track,whereby the coal is discharged into the chute and from thence delivered to the car.

To use my device in connection with a car 4, I attach the ropes or cables to eyes 5,which are now ordinarily provided on all cars of this kind, since it is frequently desirable to mounted a drum 8 and an operating-wheel 9,

one end of this shaft being extended beyond the said rail andhas mounted thereon a bandwheel 10 to receive the brake-band 11, having its one end fastened to the pin or stud 12 on the side rail and its other end connected to the lower end of the brake-lever 14, pivoted to the side of the frame and having a spring-pressed locking-rod 15 to engage with the segment-rack 16, carried by said frame, as in the usual construction of levers of this type. Also journaled in the side rails of the frame, and approximately central thereof, is a shaft 17, on which is mounted a drum 18, carrying ratchets 19 20 on its respective ends. The ratchet 19 is engaged by a. pawl or dog 21, pivoted to the operatinglever 22, which latter is loosely mounted on a shaft 17, and said pawl or dog being held normally in engagement with the ratchet 19 by a spring 23 and held out of engagement by means of a cam 24, pivoted to the lever 22 and'provided with a suitable handle 25 for operating the cam to throw the engaging end of the pawl or dog 21 upwardly out of engagement with the ratchet 19, as will be ap parent by detail view, Fig. 5. The drum 18 is loosely mounted on shaft 17 and has connected to its one end one member of. the clutch 26, the other member of said clutch being connected to the side of the pinion 27, carried by the drum 28, that is keyed on the shaft 17. This shaft 17 extends through one of the side rails and has mounted on said extending end a band-wheel 29, adapted to be engaged by the brake-band 30, that has its one end attached to the pin or stud 31, carried by the sidelrail, and. its other end attached to the lower end of the brake lever 32, pivoted to the frame and having a spring locking-lever for engagement with the segment-rack 33, the said spring locking-lever being of the same form as shown for the spring-lever 14 and which is a construction we'llknown in the arts.

The clutch 26 is engaged whereby to shift the drum 18 and engage or disengage the clutch members by the engagement of the yoke end 34 with the movable clutch member carried by the drum 18, the said yoke end being carried by a substantially L-shaped lever 35, pivoted on the arm or support 36, carried by the frame. Pivotally connected to the outer end of the lever 35 is a connectinglever 37, having its other end pivotally attached to the operating-lever 38, which is provided with a spring-pressed locking-rod adapted to engage with the segment-rack 39, carried by the frame.

Journaledin the side bars of the frame, just back of the shaft 17, is a shaft 40, having a portion 41 square in cross-section, on which is slidably mounted a pinion 42, having an integral collar 43, with which the yoke end of the shifting lever 44 is engaged, the said lever being pivotally supported on cross-bar 45 of the frame. This shaft 40 carries a ratchet 46, which is keyed on the shaft and is straddled by the bifurcated end 47 of the operating-lever 48, loosely mounted on the shaft, the said bifurcated end of the lever 48 carrying a pivoted dog or pawl 49, held in engagement with the ratchet by means of a suitable spring 50. Near the opposite end of. the shaft 40 there is keyed thereon a ratchet 51, having an operating-lever 52 straddling the ratchet 51 and carrying a dog or pawl 53, held in engagement with the ratchet by the spring 54 in the same manner as above described for the lever 48. Also keyed on the shaft 40, adjacent the ratchet 51, is a ratchet or gear55, which is engaged by a spring-pressed dog or pawl 56, pivotally supported from the side rail of the frame. This ratchet or gear 55 and pawl or dog 56 prevent backward movement of the shaft 40 when actuated by levers 48 52 being operated so as to cause their pawls to engage ratchets For normally holding the slidable member of the clutch 26 in engagement with the memher carried by the ratchet 27 I providea spring 57 on the shaft 17, between the one side rail of the frame and lever 22, and for elevating the dog 58 out of engagement with the ratchet 20 when the members of the clutch 26 are disengaged I provide a camfinger 59, which is carried bythe supportingarm 36. v The dog 58, which engages ratchet 20, is pivoted to the L-shaped arm 35. For the purpose of preventing the band-wheels 10 29 from becoming slippery, due to inclement weather or other causes, I provide a sanding device for these wheels comprising a hopper 60, supported by standards 61, attached to the frame of the machine. This hopper is provided in its. bottom with two outlet-ports controlled by the valves 62 63, pivoted to the bottom, and which are operated by rods 64 65, extending through the side wall of the hopper and pivoted to said valves and supported near their outer ends by a standard 66, attached to the cross-bar- In describing the operation attention is directed to Figs. 1, 2, 3. In the latter View all parts are shown in their normal position, the pinion 42 being shifted so as to be disengaged from gear 27 and the movable member of clutch 26 being engaged with the member carried by said gear 27. The rope or cable 69, attached to drum 18, is passed over a pulley 70, supported at one end of the frame, and then carried over a pulley 71, suitably arranged in the tipple, (see Figs. 1 and 2,) and connected to one of the eyes 5 at the rear end ofthe car 4. The rope or cable 72, attached to drum 28, is passed down over a pulley 73, carried by two beams or sills 1, and hooked into one of the eyes 5 at the forward end of the car. The rope or cable 74, attached to the drum 8, is carried over pulley 75, arranged in a suitablemannerin thetipple at the beams or sills 1, the hook in the end of said rope being engaged in an eye 76, arranged in the tipple at a suitable point.

Now if it is desired to permit the car to move forward, assuming one end to have been filled, the operator by actuating lever 32 loosens brake-band 30 off brake-wheel, and where the car is on an inclined track and the brakes of said car are off or loosened the car will drift or move forward, unwinding rope or cable 72 from its drum, until such time as the car has moved forward the desired distance, when the operator by tightening brakeband 30 on brake-wheel secures the cable and stops the car. At the same time while shaft 17 is revolving rope or cable 69 is being wound on its drum 18, due to the drums being at this time connected together by the clutch 26. This step is continued until the car has been loaded unless at any of the operations the car is moved a greater distance than desired, in which event the operator actuates lever 44 so as to shift pinion 42 into engagement with gear 27. Lever 38 is then actuated so as to disengage the clutch members, accomplished through the medium of levers 37 35, bringing pawl 58 into engagement with camfinger 59, thus lifting the said pawl out of engagement with its ratchet 20. This disengagement of the dog or pawl 58, it will be observed, is automatic with the disengaging of the clutch members, and after these clutch members have been thus disengaged the operator by actuating cam 24 lifts pawl or dog 21 out of engagement with ratchet 19. The brake-band must then be released, and then by operating either lever 48 or 52, or both, reverse movement is imparted to the shaft 17, whereby to cause cable 72, attached to the front end of the car, to pull backward on said car, so as to return it the desired distance, where it is held by the tightening of brakeband 30 on brake-wheel 29. When this is done, the operator actuates lever 44 again to shift pinion 42 out of engagement with gear 27, actuates level-38 to again engage the members of the clutch 26, which actuation allows pawl or dog 58 to again engage ratchet 20, and operator then turns cam 24, so as to permit dog or pawl 21 to again be drawn by its spring 23 into engagement with its ratchet 19. After the car has been filled ropes or cables 69 and 72 are disconnected from the car that has been filled and attached or connected to the succeeding car, and rope or cable 74is disconnected from eye 76, (which is merelya support,) and the hook in said rope or cable is attached to one of the eyes 5 of the car and said rope thus used for permitting the car to be passed slowly down to the desired position on the track beyond the tipple. In practice it is oftentimes customary to have the track at an incline for some slight distance beyond the tipple, and this cable 74 may therefore be used for attachment to the cars until they reach the level track at the end of the incline, where when the brakes on the car have been released for permitting the car to move forward and the car fails to drift the operator by actuating lever 22 causes pawl 21 to actuate ratchet 19 and shaft 17, and thus exert a pull on cable 69, so as to cause the car to be moved forward.

Stops 77 may be provided on the frame for holding the lever 44 in its different positions, if desired or found necessary.

The hand-whee1 9 on the shaft 7 forms a means for rewinding the rope or cable 74 onto its drum 8 after the loaded car has reached the point at which it is to be left standing and the said rope or cable 74 has been detached therefrom. The movement of the car down the incline to the point where it is to be left standing is controlled by means of the brake-band 11, brake or band wheel 10, and lever 14. The provision of the sanding device enables me to keep the band-brakes in condition for proper working at all times, irrespective of the condition of the Weather.
